Hello @Lundmark and welcome to our o2 community :-)

If a bill is higher than usual you should normally find an explanation for it on the monthly invoice. It may have to do with mobile connections, another possibility is that time limited rebates ended and hence the monthly amount to be payed increased.

Were you already able to have a look at the invoice, for example by using our Mein o2 app on your smartphone? :-)

Regards,

Lars

Thanks to answer, but my mobile were on Airplane mode!

I would like to have assistance in English by email, can you please write down the email address ? 

Regards,

Lundmark

o2 does not provide support via Email. If you feel the invoices are incorrect you need to submit an objection in writing within 8 weeks of the invoice date. What were you charged for? Data or telephone calls? Were you outside the EU?

@Lundmark If you need assistance over voice than call the English speaking hotline from o2.

Hello @Lundmark,

if your mobile phone was in airplane mode for the whole time then there are a number of other possibilities like the already mentioned discounts that have ended. Were you already in touch with our customer service and were your questions answered? :-)

Regards,

Lars
